Where C10100 rod goes

APPLICATIONS.

  • Fine & ultra-fine wire drawing — magnet wire, enameled wire
  • Power cable and building wire
  • Busbar manufacturing feedstock
  • EV wiring harnesses and motor windings
  • Automotive and e-mobility charging infrastructure
  • High-frequency RF connectors and waveguides
  • Aerospace and defense — drawings that mandate C10100 by name

Quality assurance

EVERY COIL.
EVERY LOT.

  • Visual inspection — surface defects, cracks, micro-holes
  • Oxygen content verification ≤5 ppm by chemical analysis
  • Electrical conductivity testing per production diameter
  • Bend test — hydrogen embrittlement immunity confirmation
  • Chemical composition certification available per lot

Storage & ordering

HOW TO
ORDER.

  • Specify diameter and coil weight when ordering
  • Store coils in a dry, covered area — prevent surface oxidation
  • Sling- or fork-compatible pallets rated for 6,000–8,000 lb
  • Custom packaging in size and weight available on request
  • Custom diameters outside standard range — contact us
